This partially holds the heads 16 and associated parts in a retracted or inoperative position. It will be noted that each of the hooks 20 is provided with a spring 21 for holding the hooks normally in a predeterm ned position, but allowing a resilient movement therefrom when the lugs 19 move outwardly, and also'when the ring 22 is partially rotated. The ring 22 is provided with a pin 23 for each of the hooks 20 so as to move the hooks 20 out of engagement with the lugs 19 and therebyallow the heads to resume their engagement with hearing member- 5. A suitable hand operated lever 2a is provided for permitting ready operation of the ring 22. As shown'in Figs. 2 and 5 pins 25 are also pro vided which extend through slots 2G for-limiting the movement of ring 22. As shown in Fig. 6 the bearing member 5 is provided with an annular flange 2'7, and also with a plate 28 which may be removed,

plate 28 and flange 27 overlapping somewhat the body 8 so as to provide a track for properly supporting body 8, and for preventing body 8 and associated parts from becoming disconnected with the bearing member 5. Whenever the hooks 20 are in engagement with the lugs 19 the device cannot be operated for turning o er the engine. On a proper" movement of lever 24, the hooks will be disengaged from lugs 19 and the heads 16 will automatically move into engagement with the bearing member 5, whereupon crankiS) may be operated for turning over the engine, which when turned over will nausea rotation of bearing'member 5 and a rotary outward movement of the heads 16 which; will again become locked in their outer position. If the engine should backfire the only result would be that the heads 16 would be forced outwardly and the lugs 19 inte engagement with hooks 20 which would necessitate a manual release thereof before the engine couldbe properly turned over. While the engine is rnnning the body 8 and associated parts swing freely on the bearing member. 5 so as to always be in place whenever it is desired to crank the engine. v In order that the various parts may not be clogged with dirt or other foreign matter a protecting plate 29 is secured to what may be termed the rear face ofthe body 8 and a covering plate 30 is secured to the front face of body 8, these plates being preferably held in place by suitable screws-as shown in Fig. 2.

What I. claim is:-

1. In a cranking device of the charrcter described, a bearing member connected with the shaft of an en ine, a body rotatably "*"i'nounted on said bearing member,

a plurality of s ring pressed members arranged in sand b0 y and engaging said bearing memnembers out of engagement with place on said bearing member, aplurality ofmean? when moved therefrom and a single manually actuated member for disengaging said 7 looks from said spring pressed members.

2. In a cranking device for engines, the! combination with the engine shaft, of a bearing memberconnected therewith, said bearing member having a plurality of notches a rotatable body arrangedfjon said bearing member, 'a plurality of reciprocating members having rounded end fitting into said notches, said reciprocating members being arranged to move in and body with the end projecting into said [notches, a spring for each of said reciprocating means for resiliently pressing the reeiprocating means into engagement with ,sa,d bearing member, a plurality of pivotally mounted hooks, and means extending from each of said reciprocating members for engaging said hooks for looking they reciprocating said bearing member when moved therefrom.

3. In a cranking device of ,the character described, a bearing member adapted to be connected with the shaft of an engine, said bearing member being formed with a pair of flange members and with a plurality. of 95 sockets, a manually operated body loosely mounted on said bearing member with parts projecting into the space between said flanges whereby said'body is loosely held in reciprocating pins arranged in said body, each of said pins having rounded heads adapted to be inserted into said notches, a spring pressing against each of said heads for normally pressing thesame into said notches, means for varying thei tension of said springs,,a stop or lug projecting from each of said heads, and a leaking member adapted to engage said pin or projection when moved radially until said heads have moved out of said notches, whereby said body is disconnected from said bearing member. i. In a device of the character described, a bearing member provided with-fa plurality of notches in the periphery thereof, a manually operated body journaled in s id bear" 1 ing member, a plurality of spring pressed reciprocatin pins arranged in-fsaid body,

lugs and hold the heads out of engagement 13 0 with said bearing member, and

operated means for disconnecting said hooks irom said lugs.

5. In a cranking device of the character described, a bearing member adapted to be connected with the shaft of an engine, said bearing member having a plurality of rounded notchestherein, a manually operated body arranged on said bearing member, a crank member for actuating said body, a @lurality of reciprocating spring pressed pins arranged on said body, and adapted to project into said notches, the ends of said pins extending into said notches being rounded, whereby a pressure greater than the tension of the springs will cause the pins to move radially out of said notches, a hook co-acting with each of said pins for locking the same in a position out of engagement with said bearing member, a manually operated ring, and a pin extending from said ring and engaging each of said hooks for unlocking the hooks from said pins.

6. In a device of the character described,

operated body a bearing member adapted to be connected with the shaft of an engine, a manually journaled in said bearing member, spring pressed traction members carried by said body and partially engaging said bearing member whereby whenever said body is rotated and said traction members are in engagement with said bearing memher the bearing member will also be rotated, :1 lug projecting from each of said bearing members, a pivotally' mounted hook adapted to engage said lugs when the traction members are moved out of contact with said bearing members, and manually actuated means for simultaneously disengaging all of said books from all of said lugs or projections so as to release said traction members.

In testimony whereof I have signed my name to this specification in the presence of tWo subscribing Witnesses.
